COURSE OBJECTIVES

In the past decade there have been many developments in new structural steels aimed at a variety of applications such as automotive applications pipelines and building applications. This course will be aimed at linking a fundamental understanding of the compositions and heat treatments required to produce a variety of materials such as Dual Phase steels , TRIP and TWIP steels ,nanograined steels, high strength bainitic steels and new martensitic grades to their mechanical properties. The course is open to academic and industrial participants. Students who are taking the course for academic credit will be asked to prepare a report on a relevant topic. The course will count for a half-unit. The grade will be based on the report and the presentation on the topic. The presentations will take place during the week of July 16, 2012.

COURSE STRUCTURE

The course will be divided into 3 modules dealing with:

  • The development and characterization of modern structural steels in terms of the factors controlling their microstructures, their characteristic length scales and their relationship to engineering requirements.
  • A module will be devoted to descriptions of the strengthening mechanisms of these steels including modeling of their mechanical response at the continuum and dislocation levels. The models will include consideration of the combinations of yield strength, workhardening and Bauschinger effects in a wide range of steels.
  • The third module will be devoted to a treatment of basic fracture mechanics and its application to structural steels using both Linear Elastic Fracture mechanics and Elasto-plastic models to discuss a variety of toughness parameters and their application to engineering design requirements.

Olivier

Olivier Bouaziz, Ph. D. from Joseph Fourier University (Grenoble) Leader for research on "Microstructure-Mechanical behaviour relationships" for internal studies and for the alliance between ArcelorMittal and Nippon Steel Scientific expert since January 2008 for short and mind term products development Breakthrough solutions: Ultra-fine grain steels, steel matrix composites, functionally Exploratory research leader (2005-2008).

Weck

Arnaud Weck, PHD from McMaster University. Assistant professor at the University of Ottawa.
A highly accomplished young researcher with an impressive publication record focused on the relationship between microstructure and mechanical properties in materials. In particular, A. Weck has performed very innovative work on experimentally investigating the strength and ductile fracture response of materials. His expertise also includes modelling the ductile fracture process using analytical models as well as numerical tools (finite element method) coupled with local and nonlocal damage models.
